Application filed October 1,1914. Serial No. 864 420.

To all whom it may concern:

Be it known that T, SIDNEY RosENrELD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Processes of Uniting Bushings to Metal Bodies, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to bushings and to the manner of forming the connection be tween such bushings and the cooperating metallic articles (such as the bodies or heads-of barrels, cans, or kegs) whereby a close, non-leaking connection may be formed between each bushing and the surrounding metal body and whereby this connection may be formed in a particularly economical and eflicient manner.

Further objects of the invention will appear hereinafter in connection with the detailed description and will be embodied, i'n their essential combinations, in the claims attached hereto.

Referring to the drawings, Figure 1 represents a perspective view of my bushing prior to its application to the cooperating metal body; Fig. 2 a-perspective view of the metal body as prepared for the reception of the bushing; Figs. 3 and 4 details in section illustrating the manner in which the bushing is secured in place; and Fig. 5 a perspective view of the bushing and the surrounding metal body to which it is united.

While the invention disclosed herein is capable of general application wherever it' may be desirable to unite a hollow or tubular article to a metal sheet or body, it is particularly useful where thetubular body is a bushing and where such body is internally threaded for the reception of an externally threaded body, such as a faucet or a plug; -since, through the manner of uniting the bushing to the metal body, not only is a tight or leak-proof joint provided between the exterior surface of the bushing and the metal body, but this connection is not endangered through the rotary or torsional strain which may be applied to the bushing through the screwing or unscrewing of the faucet therewithin.

Describing by reference characters the various parts illustrated'herein, 1 represents the body of an internally threaded bushing, the internal thread being represented at 2. The bushing is provided with a base flange 3 projecting therefrom intermediate of the ends thereof. For convenience of descriptions, it will be assumed that the bushing occupies a position wherein the threaded bore will extend in a vertical direction, and the terms top, bottom, upper and lower will be used in accordance with this assumption, it being understood, howi ever, that I do not propose thereby to limit the use of the bushing to such vertical posi tion of the bore or axis. of the bushing is concaved from the top thereof to the outer edge of the flange 3, whereby there will be a progressive diminution in the thickness of the body from the flange 3 to the upper end of the body. The bottom of the bushing body extends below the flange, as shown at 4. The outer wall of the bushing is substantially concentric with the inner wall, with the exception that a suitable number of ears or lugs 5 are provided, which lugs or ears project laterally beyondthe outer wall and preferably extend from the top of the bushing body to and merge with the flange 3. These lugs or ears are preferably of the shape shown in. Fig. 1, having a vertical outer face 5 and vertical side faces 5", the face 5 being preferably parallel with the axis of the bushing and the faces 5 being shown as substan: tially parallel to each other-although any other angular form may be given to these lugs or cars.

6 denotes a metallic shell or body to which the bushing is to be applied. This shell or body may be the head or curved side of a barrel or keg, or any other article. The metal body 6 is shown as having an aperture 7 therein, said aperture being preferably circular and :of slightly greater diameter than the diameter .of the bushing adjacent to the flange 3. The aperture 7 is provided with lateral notches or recesses 8 corresponding in shape to the lugs or ears 5 The outer surface 1 mediate between the inner and the outer diameter of the bushing body 1. The bottom of the die 9 is fiat or plane as indicated at 10. This die member 9 is provided with a .reciprocable plunger 11 having an operating rod or stem 12.

13 denotes the fixed or bottom member of the die, said die having an annular recess 1 1 which is adapted to receive the lower portion of the flange 3 of the bushing and the part of the bushing body therebeneath, indicated at 4;

In operation, the bushing will be inserted into the opening 7 of the metal plate with the lugs or ears 5 within the corresponding recesses 8 and the top of the flange 3 against the bottom of the plate or body 6. The bushing andplate will then be applied to the die member 13 in the manner shown in Fig. 3. The die head 9 will then be forced downwardly, whereupon the inner edge of the bottom face 10 of this die will engage the outer portion of the top of the bushing body 1, along the dotted line 15 shown in Fig. 1. This will result in forcing the outer portion of the'bushing body downwardly and outwardly, the die member 9 exercising a sort of shearing action on the metal at the exterioryportion of the body 1 and spreading it into close engagement with the wall of the aperture 7 in the plate 6, and also spreading the lugs or ears 5 outwardly in like manner, but without affecting the internal diameter of the bushing. The aperture 7, the height and outer diameter of the bushing body 3, and the internal diameter of the guide member 9 will be such that, when this member strikes the plate 6 (as shown in Fig. 4) the metal forming the outer portion of the bushing will have been spread outwardly to completely fill and tightly fit against the wall which bounds and defines the aperture 7. The walls or faces of the lugs 5 will be forced in like manner intotight engagement with the walls of the notches 8 and a tight and leak-proof joint Will be formed between the bushing and the surrounding metal plate. Furthermore, because of the interlocking between the lugs 5 and the notches 8, this joint will not be disturbed through the torsion exerted upon the bushing by threading a body thereinto. Should the bushing member adhere too closely to the movable die member, the plunger rod 12 may be operated to disengage these parts.

From the foregoing description it will be apparent that I have produced a bushing and a mode of connecting the same to a surrounding metal body which will enable the connection to be made in a particularly eflicient and economical manner.

Having thus described my invention, what I claim is 1. The method of uniting a metallic body to a surrounding metallic body which consists in inserting the first mentioned body into an aperture within the second body and compressing the outer portion only of the first body in the direction of the axis thereof, whereby such outer portion is spread radially and outwardly into engagement with the surrounding body, thereby to form a close connection therewith.

2. The method of uniting a hollow body having a laterally projecting flange with a metal plate which consists in providing the plate with an aperture of greater diameter than the external diameter of the body but of less diameter than the flange, inserting the hollow body into the aperture, with the flange in engagement with one of the faces of said body, and compressing the outer peripheral portion of the hollow body whereby such outer portion is spread radially and outwardly into engagement with the surrounding body thereby to form a close connection therewith.

3. The process of uniting a metal body having a flange and a reduced extension with a metal plate which consists in providing the plate with an aperture of less diameter than the flange but of sufiiciently greater diameter than the reduced extension to receive the latter therewithin, the reduced extension having one or more laterally extending lugs and the plate having one or more corresponding notches extending from the aperture, inserting the reduced extension into the plate aperture with the lug or lugs in operative relation to the notch or notches and with the flange in substantial engagement with one face of the plate, and thereafter subjecting the ends of the body to compression whereby the reduced portion is spread radially outwardly, bringing the said reduced portion and the projecting lugs into close and locking relation to the surrounding plate.

4. The process of uniting a hollow metal body having a flange and a reduced extenson with a. metal plate which consists in providing. the plate with an aperture of less diameter than the flange but of sufliciently greater diamter than the reduced extension to receive the latter thcrewithin, the reduced extension having one or more laterally extending lugs and the plate hav- 1, 190,803 still ing one or more corresponding notches extending from the aperture, inserting the reduced extension into the plate aperture with the lug or lugs in operative relation to the notch or notches and with the flange in substantial engagement with one face of the plate, and thereafter Compressing an outer annular portion of the hollow body, whereby such outer portion is spread radially outwardly, bringing the same and the 1a projecting lugs into close and locking relation to the surrounding plate.

In testimonv whereof, I hereunto affix my signature in the presence of two witnesses.
